在SQL Server中，要将在表的列上创建的索引改为页面压缩，以下哪项代码是有效的？( )
ALTER INDEX Index_Product ON Table1 WITH ( DATA_COMPRESSION = PAGE ) GO
ALTER INDEX Index_Product ON Table1 SET ( DATA_COMPRESSION = PAGE ) GO
ALTER INDEX Index_Product ON Table1 REBUILD WITH ( DATA_COMPRESSION = PAGE ) GO
ALTER INDEX Index_Product ON Table1 REBUILD SET ( DATA_COMPRESSION = PAGE ) GO
